Question 53
Ajay can do painting in 12 days. Amit is 70% more efficient than Ajay. What is the number of days Amit would need to finish the same painting?
Solution
Let the efficiency of Ajay be 10 units per day
Then, The efficiency of Amit will be 170% of 10 = 17 units per day.
Ajay can do 10 units in 1 day.
Then, In 12 days, Ajay can do 120 units of work.
Hence, Total work = 120 units
Amit can do 120 units of work in $$\dfrac{120}{17} = 7\dfrac{1}{17}$$ days.
